Defensive publication

ABSTRACT

THIS INVENTION RELATES TO A NEW AND IMPROVED CIGARETTE PROCESSES FOR PROVIDING MULTICOLOR PHOTOGRAPHIC REPRODUCTIONS WHEREIN SILVER IMAGES ARE DEVELOPED IN EPOSES FILTER MADE FROM A CRIMPED TEXTILE TOW. THE FIBERS WITHIN THE FILTER ARE COATED WITH A SOLUTION OF GLYCEROL AND POLYPHOTOGRAPHIC ELEMENTS HAVING AT LEAST TWO SUPERPOSED HYDROPHILIC COLLID LAYERS CONTAINING SILVER HALIDE, AND (ETHYLENE GLYCOL). THE FUNCTION OF THE COATING, OR ADFORMING DIFFERENTLY COLORED DYE IMAGES IN PROPORTION TO DITIVE, IS TO INCREASE THE EFFICIENCY OF THE FILTER FOR RETHE SILVER IMAGES. THE INVENTION PROVIDES AN IMPROVEMOVING TAR AND NICOTINE FROM CIGARETTE SMOKE. BY APPROPRIATE CHOICE OF GLYCEROL AND POLY(ETHYLENE GLYCOL) MENT IN SUCH POCESSES WHEREBY UNDERCUT INTERIMAGE EFFECTS ARE OBTAINED IN AT LEAST ONE OF THE DYE IMAGES. CONCENTRATION ON THE FIBER, THE AMOUNTS OF BOTH TAR AND NICOTINE DELIVERED BY A FILTER CIGARETTE CAN BE ADJUSTED THESE UNDERCUT INTERIMAGE EFFECTS ARE OBTAINED BY INTROOVER A SIGNIFICANT RANGE. DUCING A COMPOUND SELECTED FROM THE GROUP CONSISTING OF 283-DIMETHYLTHIAZOLIUM SALT, S-B-HYDROXYETHYLTHIOUREA, 1-(2-MERCAPTOETHYL)-1,4,4-TRIMETHYL PIPERAZINIUM SALT, 2THIOBARBITURIC ACID AND 6-B-CARBOXYETHYL -4- HYDROXY-2MERCAPTOPYRIMIDINE.

T909,02]l CIGARETTE FILTER John E. Kiefer, Proflit Acres, Kingsport, Tenn. 37663, and Robert C. Mumpower II, 2104 King Mill Pike, Bristol, Va. 24201 Filed Aug. 24, 1972, Ser. No. 283,459 Int. Cl. A24b 15/02; A2411 1/06 U.S. Cl. l31--267 No Drawing. 6 Pages Specification This invention relates to a new and improved cigarette filter made from a crimped textile tow. The fibers within the filter are coated with a solution of glycerol and poly- -(ethylene glycol). The function of the coating, or additive, is to increase the efiicicncy of the filter for removing tar and nicotine from cigarette smoke. By appropriate choice of glycerol and poly(ethylene glycol) concentration on the fiber, the amounts of both tar and nicotine delivered by a filter cigarette can be adjusted over a significant range.
